HP Secure Disk Erase - White Paper

Disk Erase White Paper June 2004
Page 4
Note: Administrators will use HP Web Jetadmin 7.5 or greater which contains the latest
“plug-ins” for the HP LJ9000, HP LJ9000L, and HP LJ4100 MFP products. For more
information about HP Web Jetadmin security plug-ins, see Questions and Answers later
in this paper.)
The default disk erase mode is Non-Secure Fast Erase, and no file system access password is set.
To set a password and the secure disk erase mode, the administrator will choose the device(s)
through the Device List (double click on the device(s)) in HP Web Jetadmin (see Figure 1 earlier).
To set a system access password or select/change secure disk erase modes:
1. In the upper left of the window, choose “Configuration” from the drop-down list.
2. Click Security from the Configuration Categories list.
3. From here, administrators can:
• Type or change a new file system access password (type the password, confirm the
password, and then click Apply in the lower right corner).
• Select or change the file system erase mode (type the password, choose the desired
erase mode, and then click Apply in the lower right corner).
• Password and secure disk erase modes can be set or changed on multiple devices
simultaneously from the Device List page (select the devices, choose Configure under the
Device Tools list, and then scroll to the file system access password and erase mode).
7 Impact to Performance
The Disk Erase feature does not affect printing and typical copying including simplex, duplex,
enlargements, reductions, and n-up printing. Fast Erase is the fastest mode and is the default
today. Secure Disk Erase is slower than Fast Erase because the file data gets overwritten.
Sanitizing Erase is the most secure mode, but requires multiple overwrites of disk data and,
therefore, results in the most impact to performance. Actual performance impacts will vary.
